2.13 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This cushion shape blue sapphire weighs 2.13 carats, a carat weight that positions this stone clearly in the premium center stone category. The dimensions measure 8.19 by 6.61 by 4.42 millimeters, a well balanced spread that yields strong face up presence relative to its weight, and supports an elegant yet substantial mounting. The mixed brilliant cut has been executed to optimize both color and light return, combining a brilliant facet arrangement on the crown with carefully proportioned pavilion facets that channel light for lively scintillation and controlled dispersion. The excellent polish is evident in crisp facet junctions and a smooth table surface, which together maximize the stone interaction with light and ensure that the 2.13 carat weight reads larger on the finger than the raw number might suggest. The origin of this sapphire is Ceylon Sri Lanka, a source celebrated for vibrant blue hues and lively tone, and the enhancement is heat treated, a stable and accepted process used to refine color and clarity while preserving the underlying crystalline structure and durability of the gem. Presented by The Natural Sapphire Company, this stone exemplifies the way a precisely executed cut and calibrated proportions amplify the visual impact of a carefully weighed 2.13 carat sapphire.

Color performance in this specimen is a defining characteristic, described as vivid intensity, with a primary blue hue that leans toward the classic Ceylon spectrum while maintaining a rich saturation that avoids heaviness. The mixed brilliant cut has been selected specifically to enhance the perceived saturation and uniformity of color across the table and crown, while the pavilion configuration prevents excessive light leakage that can wash out tone in lighter sapphires. Under standard lighting the stone exhibits lively return and measured pleochroic tendencies, a subtle shift in color when viewed from different angles that is typical of natural corundum and which contributes to depth and complexity. The clarity grade is very very slightly included evaluated at eye level, which means that at typical viewing distances the stone reads as eye clean, with only minute inclusions that are primarily visible under magnification or to a trained observer. These microscopic inclusions do not interfere with brilliance or durability, and in some cases they provide internal fingerprints that can corroborate natural origin and provenance. The excellent polish ensures that even with a high level of transparency the surface finishes do not introduce haze or optical disturbances, preserving the crispness of facet reflections and enhancing overall light performance.

Craftsmanship and practical considerations have been carefully balanced in this 2.13 carat cushion sapphire to deliver a premium product that performs both aesthetically and structurally. The pavilion depth and crown height have been calibrated to optimize light return while preserving table size that flatters most setting styles, making the stone highly adaptable to halo settings, solitaire designs, or bespoke creations that demand a prominent yet refined centerpiece. Heat treatment has been applied following industry best practices to stabilize color and clarity enhancements, and because this is a standard, permanent treatment it does not compromise long term stability or care routines. Routine care consists of gentle cleaning with lukewarm soapy water and a soft brush, avoiding abrupt temperature shocks and harsh chemicals, and for added security we recommend professional inspections of any mounting to confirm prong integrity. The Natural Sapphire Company provides full provenance information and photographic documentation, and our gemologists are available to discuss the 2.13 carat weight in relation to mounting choices, finger size, and visual goals, ensuring that clients understand how the stone will perform once set. For collectors and connoisseurs who prioritize precision cut, vivid Ceylon color, and an assured presence that the 2.13 carat weight conveys, this cushion shape mixed brilliant sapphire represents a compelling balance of technical excellence and enduring appeal.
